A common occurrence (unfortunately) in the brazing world is the need to join two parts together by brazing in which the brazing gap is too large – i.e., in the range of 0.010 inches (0.25 mm) or larger. Ideal brazing clearances should be a maximum of 0.000-0.005 inches (0.00-0.125mm) for most brazing filler metals (BFMs).
